n8n - strengths & limits

Strengths

  • Self-hosting keeps sensitive data inside your own infrastructure
  • AI agents and ordinary automation live in one workflow
  • Code steps prevent the visual editor from becoming a dead end

Watch out for

  • Self-hosting means you own upgrades and uptime
  • Complex workflows need real engineering discipline
  • The learning curve is steeper than simpler no-code tools

Semantic Kernel - strengths & limits

Strengths

  • Fits existing .NET and Java codebases naturally
  • Plugin model reuses functions you already have
  • Truly cross-language, unusual in this category

Watch out for

  • API surface has changed across major versions
  • Code-first, with no visual builder for non-developers
  • You still own hosting, observability and cost control

Which should you choose?

If your priority is technical teams, self-hosted automation, ai agent workflows and internal tooling, n8n is the stronger pick. If instead you care more about enterprise developers, .net and java applications, plugin architectures and ai features, go with Semantic Kernel. For most people, trying both on a free tier is the fastest way to decide - they serve the same AI Agents & Automation space but differ in workflow and output style.
